About this item

• Breathable Cotton Allows Natural Air Exchange: The open-weave fabric lets oxygen reach the starter while allowing gases to escape, promoting consistent fermentation without trapping excess moisture
• Elastic Opening Fits Standard Jars Securely: The stretchable edge conforms tightly to various jar sizes, keeping the cover in place without slipping or letting contaminants in
• Pure Cotton Construction for Repeated Use: The durable material withstands frequent washing without losing its shape, offering a reusable alternative to disposable covers
• Simple Tuck-and-Cover Placement: Just stretch the elastic over the jar rim—no clips, ties, or fasteners needed for a secure fit
• Versatile for Fermentation and Storage: Works equally well for sourdough starters, kombucha, and other fermenting projects, as well as covering bowls during proofing
• Care Tip for Lasting Performance: Machine wash in cold water on a gentle cycle and line dry; wash before first use to remove any manufacturing residue
